Home blood pressure monitoring is a convenient and inexpensive technique to monitor blood pressure in hypertensive patients. There are convincing data that home blood pressure monitoring is a good predictor of future cardiovascular risk, perhaps better than office blood pressure. Home blood pressure measurement can be standardized using validated instruments and systematic protocols; normative criteria have established home blood pressure >135/85 mm Hg as hypertensive. ⋯ Ongoing studies are evaluating management of hypertension based on home blood pressure readings compared with traditional office-based readings. Home blood pressure monitoring is particularly useful for evaluation of white coat hypertension and masked hypertension. In this article, we discuss the methodology for measuring blood pressure at home, its comparison to the other measurement techniques, the advantages and disadvantages, cost benefit analyses, and ongoing clinical trials to help define the role of home blood pressure monitoring in the clinical management of hypertension.

Adequate vitamin D status is necessary and beneficial for health, although deficiency plagues much of the world's population. In addition to reducing the risk for bone disease, vitamin D plays a role in reduction of falls, as well as decreases in pain, autoimmune diseases, cancer, heart disease, mortality, and cognitive function. ⋯ Although some have suggested increased sun exposure to increase serum vitamin D levels, this has the potential to induce photoaging and skin cancer, especially in patients at risk for these conditions. Vitamin D deficiency and insufficiency can be both corrected and prevented safely through supplementation.

Osteoporosis commonly afflicts patients with inflammatory bowel disease, and many factors link the 2 states together. A literature review was conducted about the pathophysiology of osteoporosis in relation to inflammatory bowel disease. Screening guidelines for osteoporosis in general as well as those directed at patients with inflammatory bowel disease are reviewed, as are currently available treatment options. The purpose of this article is to increase physician awareness about osteopenia and osteoporosis occurring in patients with inflammatory bowel disease and to provide basic, clinically relevant information about the pathophysiology and guidelines to help them treat these patients in a cost-effective manner.

Historically, treatment for symptomatic lower extremity varicose veins has consisted primarily of surgical stripping of pathologic veins. Over the past 2 decades, therapeutic options for lower extremity varicose veins has greatly expanded and now includes several percutaneous and endovascular techniques. This article will discuss the pathophysiology, clinical significance and current therapy for varicose veins.

Angiogenesis has become an innovative target in cancer therapy. Agents that inhibit vascular endothelial growth factor (VEGF), one of the most potent promoters of angiogenesis, and its receptor have significant implications for clinical practice. Bevacizumab, sorafenib, sunitinib and other anti-VEGF drugs are frequently complicated by mild proteinuria and hypertension. ⋯ Glomerular injury may develop from loss of VEGF effect on maintaining the filtration barrier. Adverse effects of anti-VEGF class of drugs are manageable but require close attention and follow-up. Understanding the fundamentals of anti-VEGF drugs' mechanism of action and their clinical implications is crucial when caring for patients receiving anti-VEGF therapy.
